SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010
6.11.3.11 DDR2/mDDR CK and ADDR_CTRL Routing
Figure 6-21 shows the topology of the routing for the CK and ADDR_CTRL net classes. The route is a
balanced T as it is intended that the length of segments B and C be equal. In addition, the length of A
should be maximized.

w = PCB trace width as defined in Table 6-27 .
(2)
Center to center spacing is allowed to fall to minimum (w) for up to 500 mils of routed length to accommodate BGA escape and routing
congestion.
(3)
Series terminator, if used, should be located closest to device.
(4)
CACLM is the longest Manhattan distance of the CK and ADDR_CTRL net classes.
